Hi Nikesh, Did Jeremy respond to your question? If I recall he suggested 5.01 was now working but 5.0 did not. I guess we should be adding a test for this operation to catch any future problem? Could you or Jeremy add an issue for this? Thanks Spencer.

Hi, I have updated my Nektar++ and FieldConvert -m addfld feature is not working. Segmentation fault (core dumped) keeps coming.
